zbus
----

Enables the zbus message bus library (``apps/system/zbus``, a port of the
Zephyr zbus — see :doc:`its documentation
</applications/system/zbus/index>`) with all observer types (listeners,
subscribers, message subscribers, async listeners, ISR publisher and
runtime observers), together with its example application::

nsh> zbus
zbus: publishing 5 messages to acc_chan
zbus: listener: x=1 y=10 z=100
zbus: subscriber: x=1 y=10 z=100
...
zbus: done

The cmocka test suite from ``apps/testing/zbus`` is also included and can
be used to validate the whole zbus API on the board::

nsh> cmocka_zbus_test
[==========] tests: Running 16 test(s).
...
[==========] tests: 16 test(s) run.
[ PASSED ] 16 test(s).
